名字的意思： “beak nape”1

吃：魚飛行爬蟲類侏羅紀早期嚴格來說不是恐龍

Rhamphinion was an early flying reptile that soared over what is now Arizona during the Early Jurassic. It was one of the first pterosaurs ever found in the Americas, but we only know it from a few pieces of its skull.1 2

趣味知識

Rhamphinion lived about 196 to 183 million years ago, during the Early Jurassic.1

The only known fossils are three pieces of skull: an occipital bone, part of a left jugal (cheek bone), and two teeth with a possible jaw fragment.1 2

Its name comes from Greek words meaning 'beak nape', because the fossils come from the back of the skull.1

When it was discovered in 1978, Rhamphinion was the oldest pterosaur known from the Western Hemisphere.1

The fossils were found by an expedition led by Farish A. Jenkins Jr., and the species name jenkinsi honors him.1

A nearly complete wing bone (fourth metacarpal) found nearby might belong to Rhamphinion, but scientists are not sure.1

發現: Rhamphinion was named in 1984 by Kevin Padian based on skull fragments collected in 1978 from the Kayenta Formation of Arizona. The fossils were found by an expedition from Harvard's Museum of Comparative Zoology and the Museum of Northern Arizona.1 2
仍有爭議: Scientists are not sure exactly where Rhamphinion fits in the pterosaur family tree because the fossils are so fragmentary. It might be related to Dimorphodon, but its classification remains uncertain.1
